When I retried the hplip install, I noticed that no dependencies werebeing accessed, that hplip.tcz was being installed immediately, resultingin the error message hplip.tcz failed.

In the midst of all my thrashing around, I might have installed the old hplippreviously, with the old dependencies in place. I guessed that perhapsthat might be the cause of the failure.

On another one of my machines, I started from scratch, reinstalling a freshcopy of CorePlus 9.0. This time, hplip.tcz installed fine, loading a large number of dependencies first, with hplip.tcz loaded as the last step.

My HP Envy 7640 was detected as a network printer; I installed it with theHP Envy Photo 7100 driver as the closest match. It works fine.

Many thanks to you, Rich, and coreplayer2 for guiding me through all this !!
